calculate the force required to impart to a car of velocity 30 meter per second in 10 seconds starting from rest the mass of the car is 1500 kg
kartikey96:
u=0m/s v=30m/s t=10s m=1500kg so a=30-0/10=3 as f=ma f=1500×3=4500
correct
it is correct answer

f=ma.now f= 1500×(30-0/10) N.therefore,f=1500×3=4500N
what a brilliant answer
yes
mmm....
what are you trying to saying i can't understand
nothing
ok
the side of square are 2cm and the charge of three corners are 2c,3c and -2c then find the total electric force

u=0m/s.
v=30m/s.
t=10s.
m=1500kg.
a=v-u/t.
a=30-0/10.
a=30/10.
a=3m/s2.
F=ma.
F=1500*3.
F=4500N.
